Details of one or more implementations of the subject matter described in this specification are set forth in the description below and the accompanying drawings.

Fast, efficient, and safe transportation of a delivery from its point of origin to its destination may depend on a number of factors, including the characteristics of the delivery itself (which may include fragile, liquid, or sturdy, for example), the condition of the road segments that make up the selected route (e.g., smooth, full of potholes, and/or riddled with speed bumps, and the driving behavior, or driving mode, of the vehicle (more or less fast, more or less aggressive, etc.).

Embodiments of the present disclosure provide a method comprising identifying at least one of a characteristic and an identity of an item for delivery from an origin to a destination and selecting one of a plurality of possible routes between the origin and the destination. For each of a plurality of route segments of the selected route, mapping information is used to characterize the route segment and one of a plurality of driving modes is selected for the route segment based on the characterization of the route segment and the at least one of the item characteristic and the item identity. A driving plan includes a collection of the selected driving modes corresponding to the plurality of route segments, the driving plan comprising the selected route, is provided to a vehicle. The vehicle delivers the item from the origin to the destination via the selected route using the driving plan.

Embodiments of the present disclosure further provide an intelligent delivery system for a vehicle, the intelligent delivery system comprising at least one sensing device for determining at least one of a characteristic and an identity of an item for delivery from an origin to a destination via a selected route and a mapping information module for storing mapping information including for each of a plurality of route segments for the selected route, a characterization of the route segment. A driving mode selection module is included for, for each of the plurality of route segments using the mapping information to characterize the route segment and selecting one of a plurality of driving modes for the route segment based on the characterization of the route segment and the at least one of the item characteristic and the item identity.

Embodiments of the present disclosure still further provide a vehicle comprising an onboard computer; a sensor suite comprising a plurality of imaging devices and at least one sensing device for determining at least one of a characteristic and an identity of an item for delivery from an origin to a destination via a selected route; and a mapping information module for storing mapping information including for each of a plurality of route segments for the selected route, a characterization of the route segment.

Accordingly, aspects of the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Functions described in this disclosure may be implemented as an algorithm executed by one or more hardware processing units, e.g. one or more microprocessors, of one or more computers. In various embodiments, different steps and portions of the steps of each of the methods described herein may be performed by different processing units. Furthermore, aspects of the present disclosure may take the form of a computer program product embodied in one or more computer-readable medium(s), preferably non-transitory, having computer-readable program code embodied, e.g., stored, thereon. In various embodiments, such a computer program may, for example, be downloaded (updated) to the existing devices and systems (e.g. to the existing system devices and/or their controllers, etc.) or be stored upon manufacturing of these devices and systems.

Other features and advantages of the disclosure will be apparent from the following description and the claims.

One embodiment is a system for autonomous vehicle delivery driving mode selection based on delivery contents and mapping data. In particular, the system enables selection of one of a plurality of possible driving modes that will be used by an autonomous vehicle to transport an item, or delivery, from an origin to a destination based on characteristics and/or an identity of the item being delivered and mapping data indicating a condition of various segments of the selected delivery route. Additionally, user and/or vehicle feedback may be provided during or after the delivery and may be used to update mapping data used in driving mode selection. Moreover, additional constraints and considerations, such as cost, amount of fuel available or consumed, and/or amount of time to complete the delivery may also be considered in selecting one of the plurality of possible driving modes to be used.

As shown in FIG. 1, an intelligent delivery system 100 embodying features described herein includes an autonomous vehicle 110 including a passenger interface 120, a vehicle coordinator 130, and/or a remote expert interface 140. In certain embodiments, the remote expert interface 140 allows a non-passenger entity to set and/or modify the behavior settings of the autonomous vehicle 110. The non-passenger entity may be different from the vehicle coordinator 130, which may be a server.

A remote facility 160, which may comprise a central office or back office facility, may also be provided for providing the autonomous vehicle 110 (and particularly, the onboard computer 145) with a number of different system backend functions. The remote facility 160 may include one or more switches, servers, databases, live advisors, and/or an automated voice response system (“VRS”). Remote facility 160 may include any or all of the aforementioned components, which may be coupled to one another via a wired or wireless local area network (LAN). Remote facility 160 may receive and transmit data via one or more appropriate devices and network from and to the autonomous vehicle 110, such as by wireless systems, such as 882.11x, GPRS, and the like. A database at the remote facility 160 can store account information such as subscriber authentication information, vehicle identifiers, profile records, behavioral patterns, and other pertinent subscriber information. The remote facility 160 may also include a database of roads, routes, locations, etc. permitted for use by autonomous vehicle 110. The remote facility 160 may communicate with the autonomous vehicle 110 to provide route guidance in response to a request received from the vehicle.

For example, based upon information stored in a mapping system of the remote facility 160, the remote facility may determine the conditions of various roads or portions thereof. Autonomous vehicles, such as the autonomous vehicle 110, may, in the course of determining a navigation route, receive instructions from the remote facility 160 regarding which roads or portions thereof, if any, are appropriate for use under certain circumstances, as described herein. Such instructions may be based in part on information received from the autonomous vehicle 110 or other autonomous vehicles regarding road conditions Accordingly, remote facility 160 may receive information regarding the roads/routes generally in real-time from one or more vehicles.

The system 100 functions to enable an autonomous vehicle 110 to modify and/or set a driving behavior in response to parameters set by vehicle passengers (e.g., via the passenger interface 120) and/or other interested parties (e.g., via the vehicle coordinator 130 or remote expert interface 140). In accordance with features of embodiments described herein, the system 100 further functions to enable autonomous vehicle 110 to modify and/or set a driving behavior and/or route automatically in response to delivery contents or other considerations or factors. Driving behavior of an autonomous vehicle may be modified according to explicit input or feedback (e.g., a passenger specifying a maximum speed or a relative comfort level), implicit input or feedback (e.g., a passenger's heart rate), or any other suitable data or manner of communicating driving behavior preferences.

The autonomous vehicle 110 is preferably a fully autonomous automobile, but may additionally or alternatively be any semi-autonomous or fully autonomous vehicle; e.g., a boat, an unmanned aerial vehicle, a driverless car, etc. Additionally, or alternatively, the autonomous vehicles may be vehicles that switch between a semi-autonomous state and a fully autonomous state and thus, some autonomous vehicles may have attributes of both a semi-autonomous vehicle and a fully autonomous vehicle depending on the state of the vehicle.

The autonomous vehicle 110 preferably includes a throttle interface that controls an engine throttle, motor speed (e.g., rotational speed of electric motor), or any other movement-enabling mechanism; a brake interface that controls brakes of the autonomous vehicle (or any other movement-retarding mechanism); and a steering interface that controls steering of the autonomous vehicle (e.g., by changing the angle of wheels of the autonomous vehicle). The autonomous vehicle 110 may additionally or alternatively include interfaces for control of any other vehicle functions; e.g., windshield wipers, headlights, turn indicators, air conditioning, etc.

In addition, the autonomous vehicle 110 preferably includes an onboard computer 145 and a sensor suite 150 (e.g., computer vision (“CV”) system, Light Detection And Ranging (LIDAR), RAdio Detection And Ranging (RADAR), wheel speed sensors, GPS, cameras, etc.). The onboard computer 145 functions to control the autonomous vehicle 110 and processes sensed data from the sensor suite 150 and/or other sensors in order to determine the state of the autonomous vehicle 110. Based upon the vehicle state and programmed instructions, the onboard computer 145 preferably modifies or controls driving behavior of the autonomous vehicle 110.

Driving behavior, or driving mode, may include any information relating to how an autonomous vehicle drives (e.g., actuates brakes, accelerator, steering), or a behavior of the autonomous vehicle given a set of instructions (e.g., a route or plan). Driving behavior may include a description of a controlled operation and movement of an autonomous vehicle and the manner in which the autonomous vehicle applies traffic rules during one or more driving sessions. Driving behavior may additionally or alternatively include any information about how an autonomous vehicle calculates routes (e.g., prioritizing fastest time vs. shortest distance), other autonomous vehicle actuation behavior (e.g., actuation of lights, windshield wipers, traction control settings, etc.) and/or how an autonomous vehicle responds to environmental stimulus (e.g., how an autonomous vehicle behaves if it is raining, or if an animal jumps in front of the vehicle). Some examples of elements that may contribute to driving behavior include acceleration constraints, deceleration constraints, speed constraints, steering constraints, suspension settings, routing preferences (e.g., scenic, faster routes, no highways), lighting preferences, action profiles (e.g., how a vehicle turns, changes lanes, or performs a driving maneuver), and action frequency constraints (e.g., how often a vehicle changes lanes).

The onboard computer 145 functions to control the operations and functionality of the autonomous vehicles 110 and processes sensed data from the sensor suite 150 and/or other sensors in order to determine states of the autonomous vehicles no. Based upon the vehicle state and programmed instructions, the onboard computer 145 preferably modifies or controls behavior of autonomous vehicles 110. The onboard computer 145 is preferably a general-purpose computer adapted for I/O communication with vehicle control systems and sensor systems, but may additionally or alternatively be any suitable computing device. The onboard computer 145 is preferably connected to the Internet via a wireless connection (e.g., via a cellular data connection). Additionally or alternatively, the onboard computer 145 may be coupled to any number of wireless or wired communication systems.

The sensor suite 150 preferably includes localization and driving sensors; e.g., photodetectors, cameras, RADAR, SOund Navigation And Ranging (SONAR), LIDAR, Global Positioning System (GPS), inertial measurement units (IMUS), accelerometers, microphones, strain gauges, pressure monitors, barometers, thermometers, altimeters, etc.

In certain embodiments, information collected by autonomous vehicles, such as autonomous vehicle 110, may be provided to the remote facility 160, which may establish a database or map of routes in a given area or region where use of an autonomous driving system may be permitted. Information may be collected from vehicles in real-time, i.e., as the vehicle(s) traverses the route(s) in question. Information may be analyzed by a central office of the remote facility 160 in real-time, or on a periodic basis. The information may be provided to vehicles collectively in the area, e.g., by way of a central database or map. For example, vehicles may pull route information from the database/map to determine appropriate route(s) for use of an autonomous driving system in any manner that is convenient. In some examples, a vehicle telematics unit may selectively communicate with the remote facility to determine whether a route may be used with an autonomous driving system. In accordance with another aspect of the invention, there is provided a system for communicating with a plurality of vehicles may include a plurality of telematics units installed into each of the vehicles. The telematics units are configured to collect route information as the vehicles are traveling along a vehicle route.

FIG. 2 is a flowchart of an example method 200 implemented by an intelligent delivery system according to some embodiments of the present disclosure. In step 202, characteristics and/or an identity of an item for delivery are determined. It will be recognized that this step may be performed in any number of manners. For example, the item for delivery may have affixed thereto a code (such as a bar code or Quick Response (QR) code, for example) or an RF ID that may be read by an appropriate sensor disposed within the vehicle. Alternatively, visual sensors, such as a camera, may be used to discern characteristics and/or the identity of the item. Still further, information regarding characteristics and/or an identity of the item may be provided by an individual, such as a system administrator or operator. The information gleaned in step 202 may include such information as physical state of the item (e.g., solid or liquid), a durability of the item (e.g., sturdy or fragile), and whether or not the item is perishable (and if so, within what time frame), for example.

In step 204, a plurality of possible routes between an origin of the item and a destination of the item may be identified using mapping information and one of the plurality of possible routes is selected based on one or more relevant factors.

In step 206, the condition of each individual segment comprising the selected route is determined and the information regarding characteristics and/or identity of the item as well as the condition of the individual segments of the selected route are evaluated to select an optimal driving mode for the vehicle for each of the segments. For example, if the item being delivered is fragile (e.g., a flower arrangement) and/or a liquid (e.g., a container of soup), and/or the particular route segment is bumpy (e.g., full of potholes), a more conservative (e.g., slower) driving mode may be selected for that segment. In contrast, if the item being delivered is sturdy and/or the particular route segment is in good condition (e.g., smooth), a more aggressive (e.g., faster) driving mode may be selected for that segment. For items that are neither particularly sensitive nor durable and/or a route segment that is neither particularly bumpy nor smooth, an intermediate driving mode (e.g., intermediate speed) may be selected.

In step 208, a driving plan for the selected route is provided to the vehicle, wherein the driving plan comprises a collection of the selected driving modes corresponding to the individual route segments comprising the selected route.

FIG. 3 illustrates a number of possible routes between an origin and a destination for providing a visual illustration of route segment condition information utilized by an intelligent delivery system according to some embodiments of the present disclosure. In particular, FIG. 3 illustrates a number of possible routes 300A-300C between an origin 302 and a destination 304. As also shown in FIG. 3, a number of route segments, e.g., segment 306, are characterized (or designated or identified) in mapping information as “rough.” As used herein, a “rough” route segment is one that the vehicle (and passengers or contents thereof) experiences as bumpy and/or bouncy, either constantly or intermittently, and perhaps due to potholes or other deficiencies in the surface of the route segment or other factors. A number of other route segments, e.g., segment 308, are characterized (or designated or identified) in mapping information as “moderate.” As used herein, a “moderate” route segment is one that the vehicle (and passengers or contents thereof) experiences as not particularly bumpy and/or bouncy, either constantly or intermittently, but also not particularly comfortable due to the occasional deficiencies in the surface of the route segment or other factors. The mapping information may include historical sensor data (e.g. data from vehicle suspension, accelerometers, IMUs, etc.) from vehicles previously traversing the route segment, 3D LiDAR point-cloud data of road surfaces, approximations of road quality based thereon, user feedback from previous passengers of vehicles traversing the road segment, or any combination thereof.

Finally, a number of remaining route segments, e.g., segment 310, are characterized (or designated or identified) in mapping information as “smooth.” As used herein, a “smooth” route segment is one that the vehicle (and passengers or contents thereof) experiences as comfortable and relatively free of bumps and/or bounces. As shown in FIG. 3, route 300A is the shortest route between the origin 302 and the destination 304, but includes the highest percentage of rough segments 306 (i.e., segments characterized as rough) of all the routes 300. Route 300C is the longest route between the origin 302 and the designation 304, but includes the highest percentage of smooth segments 310 (i.e., segments characterized as smooth) and the lowest percentage of rough segments 306 of all the routes 300. Finally, route 300B is not as short as route 300A and not a long as 300C and the highest percentage of moderate segments 308 (i.e., segments characterized as moderate) of all the routes 300.

Given the foregoing mapping information of FIG. 3 as an example, in one embodiment, the driving plan for delivering a sturdy item from the origin 302 to the destination 304 via the delivery route 300A would be different than the driving plan for delivering a fragile item from the origin to the destination via the same route. For example, the driving plan for a sturdy item may include a moderately aggressive driving mode for the first segment of the route, which is indicated as being rough, and a maximally aggressive driving mode for the final segment of the route, which is indicated as being smooth. In contrast, the driving plan for the fragile item may be include a highly conservative driving mode for the first segment of the route (rough) and a moderate or moderately aggressive driving mode for the final segment of the route (smooth).

Similarly, the driving plan for delivering a sturdy item from the origin 302 to the destination 304 via the delivery route 300A would be different than the delivery plan for delivering the same item from the origin to the destination via the delivery route 300C. For example, in contrast to the driving plan for delivery of the sturdy item via the route 300A, the driving plan for delivery of the sturdy item via the route 300C may include a maximally aggressive driving mode for all but the small segments of the route at the beginning and in the middle thereof that are indicated as being rough, for which the driving plan may include short interludes of moderately aggressive driving modes.

FIG. 4 is a flowchart of an example method 400 implemented by an intelligent delivery system according to some embodiments of the present disclosure. In step 402, characteristics and/or an identity of an item for delivery are determined. It will be recognized that this step may be performed in any number of manners. For example, the item for delivery may have affixed thereto a code (such as a bar code or QR code, for example) or an RF ID that may be read by an appropriate sensor disposed within the vehicle. Alternatively, visual sensors, such as a camera, may be used to discern characteristics and/or the identity of the item. Still further, information regarding characteristics and/or an identity of the item may be provided by an individual, such as a system administrator or operator. The information gleaned in step 402 may include such information as physical state of the item (e.g., solid or liquid), a durability of the item (e.g., sturdy or fragile), and whether or not the item is perishable (and if so, within what time frame), for example.

In step 404, a plurality of possible routes between an origin of the item and a destination of the item may be identified using mapping information and one of the plurality of possible routes is selected based on one or more relevant factors.

In step 406, the condition of each individual segment comprising the selected route is determined and the information regarding characteristics and/or identity of the item as well as the condition of the individual segments of the selected route are evaluated to select an optimal driving mode for the vehicle for each of the segments. For example, if the item being delivered is fragile (e.g., a flower arrangement) and/or a liquid (e.g., a container of soup), and/or the particular route segment is bumpy (e.g., full of potholes), a more conservative (e.g., slower, less aggressive braking and steering, etc.) driving mode may be selected for that segment. In contrast, if the item being delivered is sturdy and/or the particular route segment is in good condition (e.g., smooth), a more aggressive (e.g., faster, more aggressive braking and steering, etc.) driving mode may be selected for that segment. For items that are neither particularly sensitive nor durable and/or a route segment that is neither particularly bumpy nor smooth, an intermediate (e.g., moderate speed, moderately aggressive braking and steering, etc.) driving mode may be selected.

As noted above, driving behavior, or driving mode, may include any information relating to how an autonomous vehicle drives (e.g., actuates brakes, accelerator, steering), or a behavior of the autonomous vehicle, given a set of instructions (e.g., a route or plan). Driving behavior may include a description of a controlled operation and movement of an autonomous vehicle and the manner in which the autonomous vehicle applies traffic rules during one or more driving sessions. Driving behavior may additionally or alternatively include any information about how an autonomous vehicle calculates routes (e.g., prioritizing fastest time vs. shortest distance), other autonomous vehicle actuation behavior (e.g., actuation of lights, windshield wipers, traction control settings, etc.) and/or how an autonomous vehicle responds to environmental stimulus (e.g., how an autonomous vehicle behaves if it is raining, or if an animal jumps in front of the vehicle). Some examples of elements that may contribute to driving behavior include acceleration constraints, deceleration constraints, speed constraints, steering constraints, suspension settings, routing preferences (e.g., scenic, faster routes, no highways), lighting preferences, action profiles (e.g., how a vehicle turns, changes lanes, or performs a driving maneuver), and action frequency constraints (e.g., how often a vehicle changes lanes).

In step 408, a driving plan for the selected route is provided to the vehicle, wherein the driving plan comprises the selected driving modes for each of the individual route segments.

In step 410, upon completion of the delivery, information regarding the route (e.g., actual route conditions that may include sensor data as previously described) and/or a condition of the item upon delivery is provided by the vehicle and/or a user to a remote system, for example, which uses the route information to update the mapping information used to select a route and driving mode.

FIG. 5 is a flowchart of another alternative method 500 implemented by an intelligent delivery system according to some embodiments of the present disclosure.

In step 502, characteristics and/or an identity of an item for delivery are determined. It will be recognized that this step may be performed in any number of manners. For example, the item for delivery may have affixed thereto a code (such as a bar code or QR code, for example) or an RF ID that may be read by an appropriate sensor disposed within the vehicle. Alternatively, visual sensors, such as a camera, may be used to discern characteristics and/or the identity of the item. Still further, information regarding characteristics and/or an identity of the item may be provided by an individual, such as a system administrator or operator. The information gleaned in step 502 may include such information as physical state of the item (e.g., solid or liquid), a durability of the item (e.g., sturdy or fragile), and whether or not the item is perishable (and if so, within what time frame), for example.

In step 503, additional resources and/or constraints, such as fee/price, amount of fuel required, amount of fuel available, and/or a time limit in which the delivery must be made, for example, are identified. These additional resources and/or constraints may be determined based on circumstances or imposed by a user or system operator/administrator. For example, a user may indicate that a particular delivery must be made within a certain period of time. Additionally and/or alternatively, there may only be a certain amount of fuel in the vehicle to make the delivery and/or the delivery must be made for a particular fee.

In step 504 a plurality of possible routes between an origin of the item and a destination of the item may be identified using mapping information and one of the plurality of possible routes is selected based on one or more relevant factors.

In step 506, the condition of each individual segment comprising the selected route is determined and the information regarding characteristics and/or identity of the item as well as the condition of the individual segments of the selected route and the additional resources/constraints are evaluated to select an optimal driving mode for the vehicle for each of the segments. For example, if the item being delivered is fragile (e.g., a flower arrangement) and/or a liquid (e.g., a container of soup), and/or the particular route segment is bumpy (e.g., full of potholes), a more conservative (e.g., slower) driving mode may be selected for that segment. In contrast, if the item being delivered is sturdy and/or the particular route segment is in good condition (e.g., smooth), a more aggressive (e.g., faster) driving mode may be selected for that segment. For items that are neither particularly sensitive nor durable and/or a route segment that is neither particularly bumpy nor smooth, an intermediate driving mode (e.g., intermediate speed) may be selected.

In step 508, a driving plan for the selected route is provided to the vehicle, wherein the driving plan comprises the selected driving modes for each of the individual route segments.
